dedecms的数据库操作类，非常实用，在二次开发中尤其重要。 引入common.inc.php文件 require_once (dirname(__FILE__) . "/include/common.inc.php"); 获取一条记录的内容 $row = $dsql->GetOne("Select * From `blog_arctype` where id = $aid"); echo $row['id']; 将查询获取总数输出 $row = $dsql->GetOne("select count(*) as dd where typeid = $typeid"); echo $row['dd'];//输出总数 将查询的若干条记录输出 $sql = "Select * from blog_*"; $dsql->SetQuery($sql);//将SQL查询语句格式化 $dsql->Execute();//执行SQL操作 //通过循环输出执行查询中的结果 while($row = $dsql->GetArray()){ echo $row['id']; echo $row['title']; } //或者采取这种方式输出内容 while($row = $dsql->GetObject()){ echo $row->id; echo $row->Title; } 将查询的若干条记录输出 $dsql->SetQuery("Select id,typename From `blog_arctype` where reid=0 And channeltype=1 And ishidden=0 And ispart<>2 order by sortrank"); $dsql->Execute(); while($row=$dsql->GetObject()) { $channellist .= "<a href='wap.php?action=list&id={$row->id}'>{$row->typename}</a> "; echo $row->id; } 插入一条记录 $sql = " INSERT INTO `blog_member_flink`(mid,title,url,linktype,imgurl,imgwidth,imgheight) VALUES(".$cfg_ml->M_ID.",'$title','$url','$linktype','$imgurl','$imgwidth','$imgheight');";//插入记录数据库 $dsql->ExecuteNoneQuery($sql);//执行SQL操作 $gid = $dsql->GetLastID();//获取刚刚插入的id 删除一条记录 $sql = "Delete From blog_member_flink where aid='$aid' And mid='".$cfg_ml->M_ID."';"; $dsql->SetQuery($sql); $dsql->ExecNoneQuery(); //或者使用简化模式 $dsql->ExecNoneQuery("Delete From blog_member_flink where aid='$aid' And mid='".$cfg_ml->M_ID."';"); 更新一条记录 $upquery = " Update blog_member_flink set
